Definitions

  • the invention relates to a seed drill with a boom frame two opposite and one furrow Discs attached to the cantilever frame on intersecting axes or shafts are arranged so that they are in front of and below the axes diverging contact point upwards and backwards, and with two track wheels, one of which is one Disc is adjacent and at the end of a handlebar by one Axis revolves backwards and parallel or approximately runs parallel to the associated disc axis, whereby the other end of each handlebar connected to the boom frame is.
  • This seeder (US-A-4 009 668) is a precision seeder trained, d. H. it is equipped with a dosing device, the individual seeds or individual seedlings taken from a seed hopper and onto the soil in even spacing and depth. The even placement is for the later germination process of special meaning.
  • the track wheels serve as depth guidance, about the depth of the furrow cut by the slices is determined.
  • the track wheels are assigned to the disks, run on the furrow edges and also have the task press the furrow edges firmly after pulling the furrow, so that no soil after furrowing into the furrow falls behind.
  • the track wheels are arranged so that they also touch the assigned disks with their periphery or at a slight distance to them when the disks emerge from the ground wipe off any adhering earth. This then stands out the furrow edge and is firmly pressed by the track wheels. This ensures that a clean furrow is drawn into which no earth can fall back, whereby the uniform filing is guaranteed. Especially in the area of contact with the disks, however, the track wheels are subject increased wear. The track wheels must therefore be used more often be adjusted so that there is between discs and track wheels no soil or no plant residue, which makes the pulling of a flawless furrow is impaired would.
  • each link is provided with a shaft, the axis arranged parallel to the circumferential axis of the respective track wheel and the one externally threaded socket is rotatable picks up, the bush on the shaft against rotation optionally is fixable and the external thread of the socket with a Internal thread is engaged in a hole in the the boom frame connectable handlebar end of the track wheel provided is.
  • the socket can be easily locked against rotation become or turn again if after another Proposal of the invention for connecting the handlebar to the Shaft serving as a cantilever frame with screw-in thread at one end in the boom frame or in a support connected to the boom frame and at the other end is provided with a head against the externally threaded socket is in contact and this in clamped condition against the boom frame or the support presses, whereby the socket is blocked against rotation.
  • This turnstile is then released again when the shaft is in the opposite direction Direction of rotation is actuated. This can be just like that Tighten the socket with a wrench, if the head of the shaft is designed accordingly.
  • the one with an external thread Socket can also be turned slightly when it is attached to the Provide a rotating head to the end of the shaft facing the end is that can be a hexagon.
  • the socket provided with external thread can expediently be a have a greater length than the internally threaded bore.
  • the invention takes place on a shown in Fig. 1 of the drawing Precision seeder use, the one in Fig. 1 only partially shown and transverse to the working direction Main frame 10 has.
  • a main frame is in known way to connect to a tug and takes a multitude of side by side with each other arranged row units 12.
  • Each row unit 12 has a cantilever frame 14 which is independent of the adjacent one Boom frame over two extending in the working direction Handlebar 16 on the main frame 10 movable in height connected.
  • Fig. 1 of the drawing there is only one Row unit shown, and, as is well known , each row unit 12 has a seed hopper 18 and a fertilizer hopper 20 on the boom frame 14 are arranged.
  • each row unit 12 has one Metering device 22, the seeds from the seed hopper takes over and it individually over a seed tube 24 in uniform Spaces on the floor.
  • a processing device 26 is on each row unit, in Seen working direction, in front of a furrow opener 28 intended.
  • Each furrow opener 28 has a pair a V forming disks 30 on the orderly directed accordingly Rotate axes 32 or arranged on such shafts are.
  • the axes or waves intersect so that the washers touch just before they cut into the ground. This The point of contact is in relation to the working direction the axes 32 or waves and deeper than this. In work therefore cut a V-shaped groove in the Soil when the machine moves across the field in use.
  • the seed tube 24 is directed so that individual seeds behind the disc axis in the V-shaped Furrow are filed.
  • a depth control device works with the furrow opener device 28 34 together. It is in the area of the disks 30 arranged and determines not only the furrow depth but presses the furrow edges after cutting the furrow, so that earth remains don't fall back into the furrow. Furthermore she wipes off any earth residues adhering to the panes, so that these do not fall back into the furrow or impair clean furrow cutting.
  • the depth control device 34 is shaped by two track wheels 36, which are adjacent to the disks 30.
  • the two track wheels 36 are at the lower end of one up and back directional link 38 or links via shafts 40 stored, which accommodate the track wheels 36 rotatably.
  • the top The end of each link 38 is connected to the boom frame 14 a connector 42 connected to the following is discussed in more detail.
  • the track wheels 36 are in conventionally provided with tires 44, the one have a smooth tread. Even the shafts 40 or axes of the Track wheels 36 are parallel to the axes 32 of the disks 30 arranged, but behind with respect to the working direction this.
  • adjustable stop becomes the travel of the track wheels limited to the boom frame 14. Because the track wheels 36 run off on the surface of the arable land when the machine is in use, controls the vertical position the track wheels to the disks the furrow depth as it is in Fig. 2 is indicated.
  • the inner edges of the rutting forest tires 44 are against the outside of the disks or have to a small distance, in the area in which the track wheels leave the ground again.
  • This area is the rear of the disc axes 32, but in front of the Spurwellenvellen 40. Through this contact or through this slight distance is the one mentioned at the beginning of this paragraph Cleaning effect achieved.
  • this area of the Slices of detached soil are rolled smooth by the track wheels. Via conical pressure rollers 46, which are immediately behind the depth control device 34 are provided, the Furrow closed again.
  • the connection device 42 for the depth control device 34 has a central support 48 attached to the boom frame 14 is connected and two substantially horizontally extending waves 50, which are from opposite Extend sides of support 48 outward.
  • the shafts are designed as long screws and are in bores the support 48 is screwed in and extend from the support 48 from slightly downwards so that the axes of each shaft 50 substantially parallel to that on the lower ends of the handlebars 38 provided shafts 40 of the track wheels 36 run.
  • the top of each track control arm 38 is equipped with an internally threaded bore 54, whose thread engages in the external thread on the socket 52. This way, by simply turning the socket 52 of the track control arm 38 depending on the inside or outside can be adjusted from the direction of rotation.
  • each screw-like design Shaft 50 is designed as a screw head 56 which in tight or tight state firmly against him the opposite end of the socket 52 abuts so that the socket against the corresponding end face of the support 48 rests or between the screw head and the front of the support is clamped so that the bushing 52 is opposite the shaft 50 then can not perform a rotary movement.
  • the wave 50 loosened, the bushing 52 can rotate on the shaft 50.
  • the sleeve 52 has a greater length than the bore 54 and protrudes at least at the end remote from the support the bore 54 over so that on the protruding part easily a hexagon head 58 can be provided on the socket 54 can. This facilitates turning over a corresponding one Key.
